Bloc d'alimentation Inter-Tech Coba CES-350B 350 W

The Inter-Tech Coba CES-350B 350 W is a bulk-packaged computer power supply unit designed for system builders and assemblers. It delivers up to 350 W of continuous power, includes a 20+4 pin ATX motherboard connector, supports 115–230 V AC input at 50–60 Hz and uses an active cooling system with a 120 mm fan. The unit holds an 80 PLUS Bronze efficiency certification and is RoHS compliant, emphasising reliable operation and energy-efficient performance without retail packaging.

Advantages

The Coba CES-350B focuses on technical quality rather than retail presentation to reduce cost while preserving functionality. It provides multiple output connectors including P4+4 and PCI-Express, features two separate 12 V rails for stable power distribution, and uses a quiet 120 mm fan for effective cooling. Its 80 PLUS Bronze certification ensures higher efficiency, which contributes to lower energy consumption and reduced operating costs.

Suitable for

• Entry-level and office desktop PCs
• System builders and bulk or custom PC assembly
• Upgrades where a 350 W PSU and basic PCI-Express support are sufficient

Key specifications

• Total power: 350 W
• Motherboard connector: 20+4 pin ATX
• 80 PLUS certification: 80 PLUS Bronze
• Input voltage: 115–230 V AC, 50–60 Hz
• Fan diameter: 120 mm (active cooling)
• Colour: Silver

How to use

Install the power supply into a compatible PC case following standard ATX mounting points and secure with screws. Connect the 20+4 pin ATX cable to the motherboard and attach additional connectors such as CPU P4+4 and PCI-Express plugs to corresponding components. Ensure the AC input matches the local mains voltage (115–230 V) and switch on the system after verifying all connections. Allow the internal 120 mm fan to run for proper cooling under load.

Recommendations

For reliable operation, use the Coba CES-350B in systems whose total component power draw remains below the 350 W rating and avoid heavy multi-GPU or highly overclocked configurations. Ensure adequate case airflow and periodic dust cleaning of the 120 mm fan to maintain efficiency and prolong service life.
